correct surface cleaning & hardening time (up to 72 hours for a perfect result)

You get the most optimal strength when the pull is in the same direction as the magnet's field - i

but they are slightly stronger than ferrite

The specific calculation will vary for each project

For example:

Magnetkassette 7x10 cm., Dyb (H) Tier1 correct surface cleaning & hardeningSmall magnetic cassette with deep pocket (1 cm.). Special measurements made specifically for use in storage units perfect for small notes that many people need to be able to easily grab or for business cards at a trade fair, where the cassette has to be a little bigger, so that it is easy to get your fingers into the magnetic cassette to grab one.
